LEAK-STOPPER FOR VESSELS.

SPECIFICATION formingpart of Letters Patent No. 312,613, dated4 February24, 1885.

Application filed June 13, 1834. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JAMES B. CoREY, of North Braddock, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Leak-Stoppers for Vessels; and I do hereby declare thefollowing to be afull, clear, and exact description thereof.

My invention relates to an improvement in leak-Stoppers for vessels; andit consists in the construction and arrangement of devices, ashereinafter set forth.

I will now describe' my invention so that others skilled in the art maymanufacture and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure l is aview of my improved tarpau lin rolled up on the roller and ready foruse.

Fig. 2 is a View showing the same unrolled over the side of the vessel,and Fig. 3 is a vertical cross-section showing the construction.

Like letters ofreference indicate like parts wherever they occur. y

I employ in my improvement a sheet of thin metal-such as iron orwire-cloth-having the inner or outer face covered by canvas, and ribs ofiron or other suitable material attached to the sheet at suitableintervals, and extending laterally across the same, the sheet so formedbeing rolled on a suitable roller, which roller may have connectedthereto weights for the purpose of unrolling the sheet against the sidesand bottom of the vessel.

In the drawings, a represents the canvas face ot' the sheet; b, thesheet of thin metal orv wire-cloth; and c, the ribs or bars of metal,which are riveted or otherwise secured to the metal sheet b, to whichthe canvas sheet a is secured by any suitable means. At one end of thesheet so formed are eyes or rings d, by means of which the sheet may besecured to the side or rail of the vessel, while the other end of thesheet is secured to a roller, c, provided at its ends with the Weightsf, secured to the roller by chains or lines on the wheels g.

Instead of the weights f, the roller e may be otherwise weighted.

"Where wire-cloth is employed instead of the 5o sheet metal, the ribs cmaybe dispensedwith. They may also be dispensed with in connection withthe sheet iron; but as they add strength and weight to the sheet andprevent it from buckling they are preferably em- 5 5 ployed.

The operation is as follows: These sheets being wound on the rol-ler asshown in Fig. 1, are portable, or may be secured to the bulwarks alongthe sides of the vessel. In case 6o of an accident, or when it isdesired to close an opening in the sides or bottom of the vessel, bycasting loose the roller e and dropping it over the side ofthe vessel,the roller unwinding, the sheet is brought over the opening, 65 which isclosed thereby, owing to the pressure of the water, until the damageisrepaired; or, where it is irreparable, sufficient time is afforded thecrew and passengers to escape.

Theadvantages of my invention are that 7o the covering, being supportedby the sheet metal or bars, or by both, or by the wire cloth or nettingor other flexible frame-work, is prevented from entering the opening inthe hull of the vessel under the force of the in- 75 flowing water, andat the same time it is capable of being rolled on a roller, so as to beeasily portable and occupy but a small portion of space; and, also, itis easily and rapidly applied when required.

A simpler forni of my improved device consists in a sheet of canvashaving secured thereto parallel strips or bars of wood or metal placedclosely enough together to afford a support to the canvas. 4 Although Ihave used the word canvas in'this specification, I do not desire tolimit myself to this particular fabric, as other and equivalentmaterials may be employed.

My improvement may be applied to all kinds 9c of boats, ships, and coaland other barges.

I am aware that it is not new to stop leaks in vessels by bags capableof being inflated, sails, tarpaulins, and matting, drawing them over theleak or aperture by lines passing un- 95 der the vessel; and I do notdesire to claim the same; v

Having thus described my invention, what I claim, and desire to secureby Letters Patent, In testimony whereof I have hereunto set is Y my handthis 28th day 0f May, A. D. 1884.,

In devices for savingleaking vessels, a sheet Composed of a layer ofcanvas or other textile I JAMES B. COREY. 5 fabric, and a, layercomposed of a metal sheet or` netting supported and strengthened by lat-I/Vitnesses: eral metal battens, substantially as and for the JNO. K.SMITH,

purpose specified. JAMES H. PORTE.
